PURPOSE:To require no clamp means, to simplify a constitution and to prevent the generation of a mistake in timing by constituting of a disk mounting part, a carrier for moving a disk to a prescribed position and a holding member for holding the disk at the prescribed position. CONSTITUTION:The carrier 11 is pressed and the carrier is stored in main body 5 without a deviation by driving a gear 3 and the rack 14 of the carrier at both ends of a motor 32 and a driving shaft 36. When the center of the disk mounted on the carrier comes to a musical performance position on a turntable 2, the last tooth of the gear 3 having a partial tooth is detached from the rack 14, a timing pin 31 abuts on a rotating claw 32, presses down it and the disk is held between a pressing-down piece 43 and the turntable 2. In such a way, the clamp means is not required, the holding member 4 can holds the disk with a slight force by using a lever, the constitution is simplified and the mistake in the timing is not generated and it is easy to assemble and a failure is reduced.
